PHP uses dropzonejs to drag and drop files to upload. How to echo the processing results to the textarea of the current page?

Modified the demo upload page of dropzonejs: (Original address: http://www.dropzonejs.com/exa...) Added a textarea. I want to realize that after the file upload processing is completed, the processing results will be echoed to the textarea. What should I do?
The following is the content of the index.php file:
<code><!DOCTYPE html>
<meta charset="utf-8">
<title>Dropzone simple example</title>
<!--
DO NOT SIMPLY COPY THOSE LINES. Download the JS and CSS files from the
latest release (https://github.com/enyo/dropzone/releases/latest), and
host them yourself!
-->
<script src="https://rawgit.com/enyo/dropzone/master/dist/dropzone.js"></script>
<link rel="stylesheet" href="https://rawgit.com/enyo/dropzone/master/dist/dropzone.css">
<p>
This is the most minimal example of Dropzone. The upload in this example
doesn't work, because there is no actual server to handle the file upload.
</p>
<!-- Change /upload-target to your upload address -->
<form action="upload_file.php" class="dropzone"></form>
<div >
<textarea class="result" rows="16" cols="265" id="res"></textarea>
</div></code>
The following is the content of the upload_file.php file:
<code><?php
echo "---start---\n";
if ($_FILES["file"]["error"] > 0) {
echo "Error: " . $_FILES["file"]["error"] . "<br />";
} else {
echo "Upload: " . $_FILES["file"]["name"] . "<br />";
echo "Type: " . $_FILES["file"]["type"] . "<br />";
echo "Size: " . ($_FILES["file"]["size"] / 1024) . " Kb<br />";
echo "Stored in: " . $_FILES["file"]["tmp_name"];
$content = file_get_contents($_FILES["file"]["tmp_name"]);
echo $content;
}
?></code>

You can get the uploaded image address through ajax and then display it
